The Super Fast Leak Stopper!

Seal leaks in minutes, without heat.

METALCLAD SpeedAlloy QS begins to harden in just seconds. It is a 100% solids, high performance polymer composite that can be used to make effective repairs to all types of pipes, tanks and equipment which must be returned to service very quickly or where shut downs are not possible.

METALCLAD SpeedAlloy QS is a two-component system. The simple 1:1 mixing ratio insures easy mixing. It cures to super tough composite.

  • Ultra Fast Curing
  • Trowelable
  • Requires No Heat
  • Unlimited Shelf Life
  • 100% Solids
  • Safe & Simple To Use

SpeedAlloy QS has an extremely fast initial set time, making it the ideal material for stopping the flow and effectively plugging active leaks. The use of SpeedAlloy QS, allows time for proper surface preparation and application of either standard SpeedAlloy or DurAlloy (over the SpeedAlloy QS) for a long-term repair.
